A three-dimensional image processing apparatus and a method of controlling power of same are provided. The three-dimensional image processing apparatus may include a display, a three-dimensional image filter disposed a prescribed distance from the display to adjust optical paths of the displayed view images, a camera configured to capture an image of a user, an ambient light sensor, and a controller configured to control the view images, the three-dimensional image filter, or the camera. The controller may determine a position of the user based on the captured image and adjust a perceived three-dimensional view of the view images based on the determined position of the user. Moreover, the controller may control an operational state of the camera and the at least one process based on the determined position of the user or a detected amount of ambient light.

Three-dimensional image processing apparatus and electric power control method of the same

A three-dimensional image processing apparatus and a calibration method of the same are disclosed. A display device displays two or more view images. A three-dimensional image filter is disposed at the front of the display device. The three-dimensional image filter has transmission regions and non-transmission regions which are alternately arranged. A controller adjusts positions of the non-transmission regions of the three-dimensional image filter based on a current position of a user and a reference switch mode. Upon detecting a user action to request movement of the non-transmission regions, the controller changes the reference switch mode in response to the user action and adjusts the positions of the non-transmission regions of the three-dimensional image filter based on the changed reference switch mode.

Three-dimensional image processing apparatus and calibration method of the same

An apparatus and a method of displaying 3-Dimensional image are disclosed. A camera unit serves to capture an image of a viewer. A position tracking device serves to detect a position of the viewer using a video frame included in the captured image and calculate a position of a non-transmissive region of a 3D image filter based on the detected position of the viewer. A display unit serves to move the non-transmissive region of the 3D image filter according to the calculated position of the non-transmissive region. Changing a sweet spot of the 3D image to suit movement of the viewer has the effects of enlarge a viewing angle of the viewer and preventing crosstalk and image flipping even when the viewer moves.
